Note A has a frequency of

fa=1,760 Hz

Note D has a period of 1,175 hertz

(the previous data should be frequency, not period)

We are required to find the ratio of A to D. Let's call it r:

[tex]r=\frac{1,760^{\prime}}{1,175}[/tex]

Dividing: r = 1.4978. Rounding to two decimal places:

r = 1.50

Now to express the answer in integer ratio form, we need to simplify the fraction.

First, we divide by 5 up and down:

[tex]r=\frac{352^{\prime}}{235}[/tex]

There are no more common divisors for both numbers, thus the integer ratio form is r = 352/235
